Customer's Satisfy is my happiness!
My background as a Web Developer, along with my education in Computer Science, have allowed me to attain a strong foundation of technical skills.

2. Back-end
- JavaScript: Node.js/Express.js, Sails.js and Koa.js
- Python: Flask, Django
- PHP: Custom PHP, Laravel and CodeIgniter, Symfony, CakePHP
- Database: MongoDB, MySQL, PostgreSQL and SQLite3
Here is my experience:

- Experience with common front-end development tools such as Babel, Webpack, NPM, etc.
- Ability to understand business requirements and translate them into technical requirements
- A knack for benchmarking and optimization
- Familiarity with code versioning tools {{such as Git, SVN, and Mercurial}}
Roman did an exceptional job testing my app. He was tasked with following different steps in the user journey and accomplishing key tasks on the platform, he completed the tasks much faster than the other developers to whom I assigned the same job. He was the fastest, most dedicated, and most communicative developer I worked with. If you're looking for a serious and professional developer with years of expertise and always looking to overdeliver to clients then look no further and hire Roman.
Other team members struggled giving him access at first. Took about a week (into a 3 week project). He requested more money for the project after agreeing to it and was given access. Then asked again for bonus after completing. Then said he had personal issues/matters and couldn't complete the project. So I'm rating based on that though I can't rate his expertise as I haven't seen it.
Set up Next.js projects, including configuring dependencies, project structure, and environment variables.
Developed reusable and modular UI components using React.
Implemented state management solutions like Redux and React Context API for managing application-wide state and data flow.
Utilized Next.js features for server-side rendering (SSR) and static site generation (SSG) to improve performance, SEO, and user experience.
